Varieties used for comparison: 'AC Morley' and 'Harvard'
Summary: The frequency of plants with recurved/drooping flag leaves is low to medium in 'Princeton' whereas it is high to very high in 'AC Morley' and high in 'Harvard'. The plants of 'Princeton' are taller than those of 'AC Morley' and shorter than those of 'Harvard'. The culm of 'Princeton' has medium glaucosity whereas 'Harvard' has strong to very strong glaucosity. At maturity, the spike of 'Princeton' is nodding whereas it is inclined in 'Harvard'. The awnlets at the tip of the spike of 'Princeton' are medium length whereas they are short on 'AC Morley'. The spike of 'Princeton' is longer than those of both reference varieties. The lower glume of 'Princeton' is medium to long whereas it is short to medium in 'AC Morley'. The shoulder of the lower glume of 'Princeton' is elevated whereas it is straight in both reference varieties. The beak of the lower glume of 'Princeton' is slightly curved whereas it is straight in 'AC Morley'. The germ of 'Princeton' is large whereas it is medium sized in both reference varieties.
PLANT: winter type, mid-season maturity
SEEDLING (at four leaf stage): absent or very weak intensity of anthocyanin colouration of coleoptile, glabrous lower leaf sheath and blade
GROWTH HABIT (at 5-9 tiller stage): erect
FLAG LEAF (at booting): low to medium frequency of plants with recurved flag leaves, no anthocyanin colouration on auricles, weak to medium glaucosity on sheath, glabrous blade and sheath
SPIKE: tapering, weak density, medium to strong glaucosity, white in colour with nodding attitude at maturity
CULM: medium glaucosity, very weak curvature at maturity
STRAW: thin pith in cross section, no anthocyanin colouration at maturity
AWNS: awnlets present, medium length, white
LOWER GLUME: medium width, medium to long, glabrous
LOWER GLUME SHOULDER: elevated, narrow to medium width
LOWER GLUME BEAK: slightly curved, short to medium length
KERNEL: hard red type, dark red, large, medium to long, medium width, broad elliptical to elliptical in shape, angular cheek, long brush hairs, large oval germ
KERNEL CREASE: medium width, mid-deep to deep
PERFORMANCE CHARACTERISTICS: fair to good winter survival, fair to good bread making quality
DISEASE REACTION: moderately resistant to moderately susceptible to Septoria tritici blotch (Septoria tritici), moderately resistant to Powdery mildew (Erysiphe graminis f. sp. tritici), Fusarium head blight (Fusarium graminearum, Fusarium species), Leaf rust (Puccinia triticina), Stem rust (Puccinia graminis f. sp. tritici)
Origin & Breeding History: 'Princeton' is the result of the cross FR227/17 x IP16/20 made in 1995 in Schwabisch Hall, Germany. Single plant selection was used from the F3 to F5 generations based on yield potential, milling and bread making quality and disease resistances. The F6 was bulked by random selection of the progeny of 600 single F5 plants. 'Princeton' was tested as ACS54037.
Tests & Trials: The tests and trials for 'Princeton' were conducted in Palmerston, Ontario during the 2008 and 2009 growing seasons. A 4 replicate RCB design was planted with each replicate consisting of 8 rows, measuring 4 metres in length, seeded at a rate of 400 seeds/square metre. Measured characteristics were based on a mean of two years, with 20 measurements recorded each year.
